Physical properties

Formation & geological history

Forms mainly in granitic pegmatites and hydrothermal quartz veins as silica-rich fluids cool, generally in Precambrian to younger continental crust. The specimen has been mechanically tumbled and polished.

Uses & applications

Used for ornamental objects, carvings, beads, cabochons, and inexpensive jewelry; it is also popular as a decorative and metaphysical stone. Common tumbled pieces have modest commercial value.

Geological facts

Rose quartz is usually massive rather than well-crystallized; transparent, well-formed crystals are uncommon. Its pink color can fade with prolonged strong sunlight or heating.

Field identification & locations

Identify it by its uniform pink color, glassy luster, hardness sufficient to scratch ordinary glass, and lack of obvious cleavage; test cautiously because scratching damages the specimen. Common sources include Brazil, Madagascar, India, South Africa, and the United States.
